DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 6 As shown, a house inspection drone according to an embodiment of the present invention includes a body 1, two sets of arms 11 are fixed on both sides of the body 1, a flight assembly 111 is installed at one end of the arm 11 away from the body 1, a camera module 2 is arranged below the body 1, a high-resolution camera and an infrared thermal camera are installed inside the camera module 2, a second protective frame 33 is arranged outside the flight assembly 111, a first protective frame 3 is arranged above the second protective frame 33, a connecting arm 31 is fixed at the top of the first protective frame 3, and the connecting arm 31 is close to the body A guide shell 312 is provided on one side of the connecting arm 31, the guide shell 312 is fixedly connected to the machine body 1, the bottom end of the guide shell 312 is fixedly connected to the machine arm 11, a slot is provided inside the guide shell 312, a slider 311 is fixed on the side of the connecting arm 31 close to the guide shell 312, the slider 311 is slidably connected in the slot, a second guide column 314 is fixed in the slot, the second guide column 314 runs through the inside of the slider 311, a fourth spring 313 is fixed at the bottom end of the slider 311, and the bottom end of the fourth spring 313 is fixedly connected to the guide shell 312; After the construction of a building is completed, it needs to be inspected. In order to facilitate the inspection, an unmanned inspection will be used. At this time, the drone is controlled by the remote control, and the body 1 powers on the flight component 111. At this time, the flight component 111 rotates to make the body 1 take off, and then the flight route of the body 1 is controlled by the remote control. During the flight, the direction of the camera module 2 is aimed at the building. At this time, the high-resolution camera of the body 1 can shoot the shape of the building, and the infrared thermal camera simultaneously performs thermal imaging of the building. The thermal imaging pattern of the building surface can be observed through thermal imaging. When there is a hollow wall on the building wall, the thermal imaging picture will be different. The difference in the picture can be used to determine whether there is a hollow wall. There may be other buildings under construction around the inspected building or there are trees around the building. At this time, the drone comes into contact with Obstacles may cause the drone to lose control. When the drone loses control, it will fall to the ground. At this time, the second protective frame 33 can protect the outside of the flight component 111, and the first protective frame 3 can protect the top of the flight component 111. When falling, the top of the flight component 111 may touch the ground. At this time, the first protective frame 3 is pushed by the ground to drive the connecting arm 31 to move. At this time, the connecting arm 31 drives the slider 311 to slide inside the groove of the guide shell 312, and the slider 311 squeezes the fourth spring 313. The fourth spring 313 can buffer the force of the ground pushing the first protective frame 3 through its own elastic force, thereby protecting the flight component 111. At the same time, the guide shell 312 can reinforce the connection between the arm 11 and the body 1, which can reduce the possibility of the arm 11 breaking when it touches the ground.

[0024] like Figures 1 to 6 As shown, a rotating block 323 is rotatably connected to the lower part of the first protective frame 3, and a plurality of protective plates 32 are fixed at equal intervals on the outer side of the rotating block 323. The first protective frame 3 is provided with notches matching the number of the protective plates 32, and the protective plates 32 can be engaged with the notches of the first protective frame 3. In daily use, the first protective frame 3 will block the top of the flight component 111. At this time, the protective plate 32 is placed below the first protective frame 3. The blades of the first protective frame 3 and the protective plate 32 can overlap. When the drone detects a fall, the rotating block 323 drives the protective plate 32 to rotate. At this time, the protective plate 32 rotates to the gap of the first protective frame 3, and then the protective plate 32 is engaged with the gap of the first protective frame 3. At this time, the first protective frame 3 and the protective plate 32 can form a complete top plate, which can block the top of the flight component 111 and further protect the flight component 111. When it rains during detection, the first protective frame 3 and the protective plate 32 can block the top of the flight component 111 and divert rainwater, which can prevent the motor of the flight component 111 from being corroded by water.

[0025] like Figures 1 to 7As shown, a lifting frame 324 is fixed to the bottom end of the protective plate 32 near the rotating block 323, and a plurality of guide grooves 326 are provided at equal intervals on the outer side of the rotating block 323. The lifting frame 324 is slidably connected to the inside of the guide groove 326, and a limiting column is fixed inside the guide groove 326. The limiting column runs through the inside of the lifting frame 324, and a fifth spring 325 is sleeved on the outside of the limiting column. The top end of the fifth spring 325 is fixedly connected to the bottom end of the lifting frame 324, and the bottom end of the fifth spring 325 is fixedly connected to the rotating block 323. In the initial state, the protective plate 32 overlaps with the first protective frame 3, and the lifting frame 324 squeezes the fifth spring 325. When the rotating block 323 drives the protective plate 32 to rotate to the position of the notch, the fifth spring 325 pushes the lifting frame 324 to rise. At this time, the lifting frame 324 pushes the protective plate 32 to rise, and the protective plate 32 can enter the notch of the first protective frame 3, so that the first protective frame 3 and the protective plate 32 can be automatically combined.

[0026] like Figures 1 to 6 As shown, a plug post 321 is fixed to the bottom end of the protective plate 32 away from the rotating block 323, a plurality of guide holes 331 are opened at equal intervals inside the second protective frame 33, the plug post 321 is inserted into the guide holes 331, a plurality of teeth 333 are fixed to the outer side of the bottom end of the second protective frame 33, a micro motor 14 is installed inside the arm 11, a gear is fixed to the end of the rotating shaft of the micro motor 14, and the gear is meshed and connected with the second protective frame 33 through the teeth 333; When the drone is about to fall or encounters rain, the body 1 will control the micro motor 14 to rotate. At this time, the micro motor 14 drives the second protective frame 33 to rotate through the gear. The second protective frame 33 drives the plug 321 to move through the guide hole 331. At this time, the plug 321 will drive the protective plate 32 to rotate, which can realize the automatic combination between the protective plate 32 and the first protective frame 3.

[0027] like Figures 1 to 6 As shown, guide slopes 322 are provided on both sides of the protection plate 32; After use, the protective plate 32 needs to be reset to the bottom of the first protective frame 3. At this time, the micro motor 14 drives the protective plate 32 to rotate in the reverse direction. At this time, the protective plate 32 can move downward under the guidance of the guide slope 322, so that the protective plate 32 can automatically move to the bottom of the first protective frame 3.

[0028] like Figures 1 to 10As shown, a storage chamber 12 is provided inside the body 1, and a lifting plate 21 is slidably connected inside the storage chamber 12. The camera module 2 is installed inside the lifting plate 21, and a lifting block 211 is fixed on the side of the lifting plate 21 away from the camera module 2. A first slide groove 121 is provided on one side of the storage chamber 12, and the lifting block 211 is slidably connected inside the first slide groove 121. A first guide column 212 is fixed inside the first slide groove 121, and the first guide column 212 runs through the inside of the lifting block 211. A third spring 213 is sleeved on the outside of the first guide column 212, and the bottom end of the third spring 213 is fixedly connected to the lifting block 211, and the top end of the third spring 213 is fixedly connected to the body 1; The camera module 2 is a relatively high-cost component in the drone, so it needs to be protected. When the drone falls, the lifting plate 21 moves toward the inside of the storage cavity 12. At this time, the lifting plate 21 can drive the camera module 2 into the inside of the storage cavity 12, so as to protect the camera module 2. In the use state, the third spring 213 will push the lifting block 211 downward, and at this time, the lifting plate 21 can drive the camera module 2 to extend out from the inside of the storage cavity 12.

[0029] like Figures 1 to 9 As shown, a reel 141 is fixed to the middle of the rotating shaft of the two micro motors 14 near the camera module 2, and a pull rope 214 is fixed to both sides of the top of the lifting block 211, and the other end of the pull rope 214 is wound around the outside of the reel 141. Rollers are provided on both sides of the top of the first slide slot 121, and the pull rope 214 passes through the surface of the rollers; In the initial state, the pull rope 214 is in a loose state. When the drone falls, the micro motor 14 will drive the winding wheel 141 to rotate. At this time, the winding wheel 141 will reel in the pull rope 214. At this time, the pull rope 214 is tightened and then drives the lifting block 211 to rise. At this time, the lifting block 211 drives the lifting plate 21 to enter the storage cavity 12. The lifting plate 21 can drive the camera module 2 into the storage cavity 12, so as to protect the camera module 2.

[0030] like Figures 1 to 9 As shown, a limiting groove 332 is provided at the lower part of the second protection frame 33, a first limiting block 112 is fixed to the outer side of the flight assembly 111, the first limiting block 112 is slidably connected to the inside of the limiting groove 332, and first springs 113 are fixed to both sides of the first limiting block 112; When the micro motor 14 drives the winding wheel 141, the second protective frame 33 is driven to rotate through the gear. At this time, in order to prevent the second protective frame 33 from jamming the gear, the first limit block 112 is set to slide inside the limit groove 332. When the second protective frame 33 drives the protective plate 32 to splice with the first protective frame 3, the micro motor 14 will continue to drive the winding wheel 141 to rotate. At this time, the gear will continue to drive the second protective frame 33 to rotate. When the second protective frame 33 rotates, it will drive the limit groove 332 to move. At this time, the first spring 113 on one side of the first limit block 112 will be squeezed by the inner wall of the limit groove 332. When the second protective frame 33 rotates a certain distance, the teeth 333 will contact the micro motor 14. The gears of the motor 14 are separated. At this time, the first spring 113 will push the inner side of the limiting groove 332 to drive the second protective frame 33 to rebound, and this cycle will continue until the winding wheel 141 completes the winding of the pull rope 214. When the protective plate 32 and the lifting plate 21 need to be reset, the micro motor 14 rotates in the opposite direction. At this time, the third spring 213 drives the lifting plate 21 to reset, and the pull rope 214 becomes loose. At the same time, the gear of the micro motor 14 drives the second protective frame 33 to reset. After resetting, the micro motor 14 will continue to rotate. At this time, the first spring 113 on the other side of the first limiting block 112 will push the second protective frame 33 to rebound in the other direction, so that the gear can drive the teeth 333 next time.

[0031] like Figures 1 to 10 As shown, a lifting block 211 is hinged at the bottom end of the lifting plate 21, a baffle 22 is fixed to one side of the lifting block 211, a rack is fixed to the side of the rotating column 221 away from the baffle 22, and a storage groove 23 is opened at the bottom end of the storage cavity 12, and a rack is also fixed inside the storage groove 23; When the lifting plate 21 is pulled into the storage chamber 12, the baffle 22 can protect the bottom of the camera module 2. When the lifting plate 21 drives the rotating column 221 to enter the storage groove 23, the rack inside the storage groove 23 will engage with the rack of the rotating column 221. At this time, the rotating column 221 will drive the baffle 22 to rotate, so that the baffle 22 is in a horizontal state, which can protect the bottom of the camera module 2. When the lifting plate 21 extends from the inside of the storage chamber 12, the storage groove 23 will drive the rotating column 221 to reset the baffle 22. At this time, the baffle 22 can be used without blocking the camera module 2.

[0032] like Figures 1 to 10 As shown, a support plate 132 is fixed to the bottom end of the flight assembly 111, a support foot 13 is arranged below the support plate 132, a telescopic plate 131 is fixed to the top end of the support foot 13, the top end of the telescopic plate 131 is inserted into the inside of the support plate 132, a second spring 133 is fixed to the top end of the telescopic plate 131, the top end of the second spring 133 is fixedly connected to the support plate 132, a guide rod is passed through the inside of the second spring 133, the bottom end of the guide rod passes through the inside of the telescopic plate 131, and second limit blocks 215 are fixed to both sides of the bottom end of the lifting plate 21; Under the limit of the second limit block 215, the baffle 22 can always be below the camera module 2. When the bottom of the body 1 falls to the ground, the baffle 22 can block the bottom of the camera module 2 to prevent the ground from hitting the camera module 2 and causing damage to it. At the same time, after the baffle 22 contacts the ground, it will push the lifting plate 21 to drive the camera module 2 to retract into the storage cavity 12, which can further avoid damage to the camera module 2. At the same time, the supporting foot 13 will contact the ground and push the telescopic plate 131. The telescopic plate 131 squeezes the second spring 133 into the inside of the supporting plate 132, which can achieve buffering and reduce the impact on the body 1.
